| Title: |
Plasma Lamp Using a Shaped Waveguide Body |
| Abstract: |
A plasma lamp for an electrodeless plasma lamp having a shaped dielectric
waveguide body. The shaped body may have a relatively thin region
containing a bulb, and a second region thicker than the first region.
Microwave probes may be positioned in the second region to provide power
to the waveguide body. The body may be shaped to intensify the electric
field in the first region adjacent to the bulb to allow operation at a
lower frequency than a solid cylindrical or rectangular waveguide body
having the same volume and dielectric constant.
